A Survey on 3D Face Modeling

In the advance of science, different disciplines are interested to study the human body, among of them we have the facial anthropometry, which studies the human face´s dimension and proportions by detecting what is called anthropometric landmarks over the facial surface. Such facial landmarks can be detected by using either direct or indirect techniques. Within a 3D face image it is generally know that the most distinctive facial landmarks are the inner-corners and the tip of the nose, although their appearance varies among human races. Hence, most face processing application generally relay on a face model for comparison and analysis based on such anthropometric landmarks. This paper presents a survey on 3D face modeling, which in the best of our knowledge is missed in relate literature and it is necessary to propose a new 3D facial model, and such model is a primary step in any face processing application. In particular, we are aim to produce a useful 3D face model for research in key areas based on Mexican anthropometric analysis.
